CARDING-ENGINE.

SPECIFICATION forming` part of Letters Patent No. 484,928, dated October 25, 1892.

Application tiled July 14, 1892. Serial No. 439,963l (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM PITT CAN- NING, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement 1n Carding-Engines, of which the-following is a specification, reference being had therein to the accompanying drawings.

My invention relates to the calender-rolls of carding-engines and the parts which are adjacent thereto and associated therewith, and in particular to the driving connections of the said rolls, the covers for the rolls, and the supporting-stands therefor.

My invention consists in certain improved features of construction and novel combinations of parts and first will be described, with reference to the accompanying drawings, and then will be particularly pointed out and defined in the claims at the close of this specification.

In the drawings, Figure 1 is a view, partly in vertical section, on the line o@ in Fig. 3, through the calender-rolls and adjacent parts of a carding engine, showing certain features of my invention, certain of the parts being broken away at the left-hand sideof the gure for want of space. Fig. 1A is a similar view showing the parts which are thus broken away in Fig. 1. Fig. 1B is a detail view of Washer 1003. Fig. 2 is a view in plan of the devices which are represented in Fig. 1, with the various covers removed. Fig. 3 is a view thereof in side elevation, also with the covers removed. Fig. 4 is a view in side elevation, illustrating the adjustable rie-gear stand and the support therefor. Fig. 5 is a view in section on the dotted line A A in Fig. 4. Fig. 6 is a view in section of the rifle-gear and its supporting and shifting devices. Fig. 7 is a view in side elevation of the rifle-gear quill. Fig. 8 is a view in section on the dotted line A A in Fig. 7. Fig. 9 is a view in vertical section on the dotted line y y in Fig. 3. Fig. [10 is a view in plan of the cover which is intended to be placed over the train of gears by which motion is transmitted to the shaft of the lower calender-roll from the doffer-gear. Fig. 11 is a view in side elevation of the said cover. Fig. 12 is a view in end elevation thereof. Fig. 13 is a view in vertical section on line A A in Fig. 1l. Figs. 14 and 15 are side and edge views, respectively, of the top cover which is employed at the left-hand end of the calender-rolls in Fig. 1. Figs. 16 and 17 are corresponding Views of the top cover which is employed at the right-hand end of the rolls in Fig. 1. Figs. 18,19, and 20 are respectively plan, side, and edge views of one of the bottoni covers. Figs. 2l and 22 are respectively a plan view of the top clearer and a vertical section on line A A of Fig. 21. Figs. 23, 24, 25, and 26 are respectively a front elevation, a plan View, a side elevation, and a rear elevation of the front plate. Figs. 27 and 2S are views in section on the lines 27 27 and 23 28, respectively, of Fig. 1. Figs. 29 and 30 are a front elevation and plan View, respectively, of the fleeceguide, which is located between t-he doffer and the trumpet, and the trumpet.

The lower calender-roll is shown at 103, the upper calender-roll at 112, the shafts of the Said rolls at 100 and 110, the calender-roll stands at 75, and 102 111 are the gears on the shafts of the calender-rolls, serving to communicate motion from the shaft 100 to shaft 110.

At 101 is the calender-shaft gear, this gear being mounted upon the end of the shaft 100, between the collar 100i on the said shaft and the washer 1003. The collar 1001 is slipped onto the reduced end of the shaft, the said end being again reduced for the reception of the Washer and the nut 1002, and the gear, collar, and washer being held on the shaft by the nut 1002. The collar is held in place on the shaft by the set-screw 1001l,and thewasher 1003, as shown in Fig. 1B, is formed with a square hole, which is tted to a square portion of the reduced end of the shaft,whereby said washer is prevented from turning on the shaft. The nut 1002 is turned up so as to compress the gear 101 between the collar 1001 and washer 1003 to the extent necessary to cause the gear 101 and shaft 100 t-o turn together until the resistance to the rotation of the shaft arising from accumulation of sliver about the calender-rolls or from other causes exceeds a predetermined amount, when the gear slips and breakage is avoided thereby. The gear 101 is in mesh with the gear 12, which latter in turn meshes with the riflegear 13, this gear being driven by the dol-fergear 14. The rifle-gear 13 is fitted to the exterior of the ride-gear quill 734 and revolves between a shoulder on the quill and the hub of the crank 735, which last is secured to the outer end of the quill 734 bya set-screw 7349. The rifle-quill is mounted on a stud 7371, formed on the stand 73, the latter being pivoted at one end on the stud 721,0n which the gear 12 turns, and being formed With a curved slot 7368, through which passes the stern of the bolt 736, which also passes through the ride-gear stand 72 and has a nut 7361 applied to the threaded end thereof on the inner side of the said stand. The stand 73 is made adj ustable for the purpose of enabling the ritiegear 13 to be kept in mesh at all times with the doier-gear 14, the said stand being moved about the stud 721 to compensate for changes in position of the doffer-gear as the doifer is adjusted with relation to the main cylinder. The stud 7371, on which the quill 734 is fitted, is chambered interiorly at 732 to receive oil, the end of the chamber being partially closed by a perforated block 731 and a radial passage being formed, as shown, eX- tending from the chamber 732 to the periphery of the stud. The quill 734 is formed with an inclined slot 7341, into which enters the end of a screw-stud 733, projecting from the periphery of the stud or stand 73. When the crank 735 on the end of t-he quill 734 is moved by means of the handle 7351 and the quill is thereby given a partial rotation, the slo't 7341 and stud 733 cooperate in occasioning movement of gear 13 outward or inward, and thereby the said gear may be moved out of mesh with gear 14 when it is desired to grind or strip the doer, and afterward may be moved back into mesh with the gear 14. The stud 721, on which the gear 12 rotates, is held to the stand 72 by the nut 7213 on the inner threaded end thereof, and on its end is affixed by the screw 72111 a collar 7211, formed with an oil-hole 72112, communicating with an inelined hole 7212, formed through the stud 721. The outer end of the shaft turns in the outer shaft-bearing 74, the latter having right and left hand projecting reduced portions, as shown, on one of which is fitted one end of a pipe 741, which extends therefrom t0 and through the outer sides of the covers 77 and 762, inclosing the gears 102 111, this pipe inclosing the shaft 100 and being held in position by the set-screw 7411. The object in forming the bearing 74 with right and left hand projecting reduced portions, as shown, is to enable castings from the same pattern to be used in either right-hand machines or left-hand machines. The shaft is set in open bearings near the upper ends of the stands 75, the said stands being formed, also,

with open bearings for the reception of the shaft 100, as clearly shown. I

To the open bearings for the shaft 100 are applied covering and retaining pieces 751, which are held to the stands by the screws 7511, so that the said pieces 751 and the shaft 100 may readily be removed after the withdrawal of the set-screws. The stands 75 are formed with projections 753 and 754, the former of which are upturned, so as to receive the hooked portions 755, projecting from the plate of the trumpet 756, and to support the said trumpetin place adjacent to the calender-rolls. The upper part of the trumpetplate rests against the projections 754, which limit the movement of the trumpet toward the rolls.

To the foregoing parts are applied various covers, some of which are shown in place in Fig. 1. In Figs. 2 and 3 the said covers are represented as omitted for the sake of clearness. The cover 760 (shown detached in Figs. 10, 11, 12, and 13) is shaped, as clearly indicated in the drawings, to enable it to be applied over the train of gears 101 12 13 and parts immediately adjacent thereto, it being adapted to inclose the said gears and adjacent parts and being cut away on the sides and at one end thereof at 7603, 7604, 7605, and 7606, to enable it to be applied over one end of the bearing 74, the plate 73, the ride-gear, and the doiier-gear, all as will readilybe understood. The cover 761 (shown detached in Figs. 14 and 15) is applied at the left-hand side in Fig. 1 and, as shown clearly in Fig. 1A, over the coiler-driving gear 104, mounted on the shaft 100, and the gear 1041, meshing therewith, it having in one side thereof a vertical slot 7611, to enable it to t over the bearing portion 1042 of the back stand 1043 of the coiler, this slot being, as shown in Fig. 14, slightly offset from the middle of the side of the cover in which it is formed in consequence of the relative position of the said coilerstand. VThe opposite side of the cover 761 is formed with a notch 7612, intended to fit over the hub of the gear 104. The cover 762 (shown detached in Figs. 16 and 17) resembles the cover 761, it differing therefrom only in the fact that it is symmetrically formed on each side thereof, the slot 7 621, as well as the notch 7622, being each at the middle of the side of the cover on which it is formed. The slot 7621 is intended to enable the cover to be passed over the shaft 110 of the upper calender-roll in iitting the cover 762 over the gears 102- 111, and the notch 7622 is intended to receive the upper side of the pipe 741. symmetrical shape of the cover 762 enables castings from the same pattern to be used on either a right-hand machine or a left-hand machine. The covers 760,761, and 762 are provided with knobs or handles 7601 7613 7623 for convenience in handling them. The covers 761 and 762 are applied from above, and there are corresponding bottom covers The IIO

77 inclosing the gear 102 and the gear 1 Q4, one of these covers being shown detached in F1gs. 18, 19, and 20. Each cover 77 is symmetrically formed, it having each lateral portion thereof identical with the other lateral portion thereof, each side having a notch 773 therein. The symmetrical shape of the covers 77 enables castings from the same pattern to be used eitherat the right-hand end of the stands 75 in connection with the gear 102 or at the left-hand end thereof in connection with lthe gear 104. The cover 77 applied at the right-hand side of the stands 75 receives in one of its notches 773 the adjacent end of the pipe 741, and the corresponding cover applied atthe left-hand side of the said stand receives in its notches the hub of the gear 104 and nut 1044, which holds the said gear on the left-hand end of the shaft 100. Each cover 77 has projecting from the opposite ends thereof yerticalguiding portions 772, which areserviceable in securing the proper application of the covers 761 762 and in preventing the latter covers from becoming dislodged. The top clearer 763 (shown detached in Figs. 21 and 22) is formed with flanges or wings having notches 7632 therein for receiving the upwardly-projecting portions which are formed at the tops of the stands 75, whereby the said clearer is held in position over the upper roll 112 and permitted to be readily removed or applied. Within the shell of the said clearer is secured a clearer-pad 7631, intended to wipe the upper calender-roll. The front plate 764 (shown detached in Figs. 23, 24,25, and 26) is provided with a clearer-pad 7641, which wipes the lower calender-roll, the said pad 7641 being placed upon the horizontal or foot portion of the said front plate and the said foot portion being slipped beneath the roll103. The said front plate is provided at the opposite sides thereof with upwardly-extending portions, as shown, which when the said plate is in place are located in front of the stands 7575 and fill the spaces between the ends of the rolls and the covers 761 762 77 77. The stands`75and covers 77 are held to the front girt 71 by bolts 752 77l,respectively, the former havingthereon the washers 7521 and nuts 7522 and the latter having thereon the washers 7711 and nuts 7712. The bearing 74 is held in place by a bolt 743, passing through the front girt 71 and side framing 70, the said bolt having upon it the washer 7431 and nut 7432. The stand 72 is secured in place by bolts 722 722, passing through the said girt 7l and side framing and having thereon suitable nuts. (Not shown.)

The trumpet, the top clearer, the covers 761 762, and` the front plate may all be quickly and readily removed without the use of tools. In order to provide for the removal of the lower roll and its shaft, it is necessary only to remove the screws 7511 and the nut 7432.

The quill 734 in practice is formed on opposite sides thereof with oppositely -inclined slots 7341, in order to adapt the saine for use on either aright-hand machine or a left-hand machine.

7561, Figs. 27 to 30, is the contracting guide, through which the fleece passes on its way from the. doffer tothe trumpet, and 7562 7562 are the converging wings or plates on opposite sides of the guide 7561.
